JORDAN L. MOTT, OF NEW YORK, N. Y.

PABLOR-STOVE.

Specification of Letters Patent No. 508, dated December 7, 1837.

To all whom it may concern:

Be it known that I, JORDAN Mom, of the city of New York, State of NewYork, have invented an Improved Parlor-Stove, which is furnished withair-heaters so constructed as to economize fuel and to supply air ofgenial warmth, which is not deteriorated in its passage through theheatingfiues; and I do hereby declare that the following is a full andexact description thereof Figure 1, in the accompanying drawing, is aperspective view of the stove. Fig. 2'is a vertical section through themiddle thereof parallel with its front; and Fig. 3, is a verticalsection from front to back, through the middle.

In each of the figures like parts are designated by the same letters ofreference.

A, is the grate, or fire chamber, which is surmounted by B, a reservoirfor coal, which hasa close fitting cover at 0, allowing a considerablequantity of fuel to be supplied at once, and to burn out gradually.

D, D, are the combined fines and air heaters, consisting of onecylinder, or rather coal tube, or chamber, within another, the innermostbeing the air chamber, and the space between it and the outermost, thesmoke flue.

E, E, Fig, 2 &c. are sections of the inner, or air, fines, and F, F, thespaces surrounding them, and forming the smoke flues. Air is admittedinto the interior, or air fine, at its lower end, through tubes, orapertures, leading into it, in any convenient way, as at the partrepresented by the dotted lines a, 4:. These tubes or apertures, may beext-ended, if preferred, so as to admit air from without the room, butthis will seldom be found necessary. The air which is heated in passingthrough the tubes, escapes into the room through openings at b, b, inthe top of the stove. v

The direction of the draft, or passage, for smoke and heated air fromthe fire, is represented' by arrows. There are, as in many other stoves,two directions for the escape of the smoke &c.; one directly to theescape pipe, and the other by a more circuitous route, which is to beused after the fuel has become perfectly ignited. There is a flat flue,Gr, extending up from the fire-place to the chamber H, at the top of thestove. In this fiat flue there are two valves, or dampers, 0, and cl, bywhich the draft is governed. L, is the escape pipe for smoke, and

into which it passes directly, when 0 is opened'and d closed; but whenthese valves are reversed, the draft is carried through the fluessurrounding the air-tubes, "and down the flue-G, to the escape pipe.Fig. 4 is a horizontal section of the stove at the level of the escapepipe, the parts of which figure are designated by their proper lettersof reference. By this arrangement of the flues, and of the air tubeswithin them, the exterior, or shell, of the stove is directly heated bythe heated air, and a free radiation takes place into the room. Fig. 5,shows a modification of the stove, in which the smoke fiues do notentirely surround the air flues, the latter being heated directly, onthe side toward the reservoir B, but still through the intermedium ofthe brick lining, which, wherever it is represented, is colored red. Inother respects, the construction of this stove is identical with thatbefore described. 7

Having thus fully shown the manner in which I construct and arrange theseveral parts of this stove, it is to be distinctly understood that I donot intend to claim the individual parts, generally, as my invention,

they having been previously known and used. All that I claim as new andfor which side fines so arranged and combined, can be advantageouslyappended, it being further understood that I make no claim to air tubessurrounded by the smoke flues, when placed immediately above the firechamber.
